5

Compare with a known intact vehicle. Is the noise the same?

6

Replace the generator assembly.

Important precaution : If a clear generator fault has not been found, make sure that all
other possible noise sources have been excluded and then replace the generator.

If the noise is part of the normal generator characteristics, after replacing generator, the noise will
not disappear.

7

Replace the drive belt or the drive belt tensioner.

Refer to 2.6.8.3 Replacement of Drive Belt or 2.6.8.4 Replacement of Drive Belt
Tensioner.

2.11.5.5 Battery Discharging Current and Parasitic Load Test

If the battery continues to loss power, perform the following test to inspect whether there are
parasitic battery current.

Note: prior to the implementation of the procedure, please firstly check whether there is
after-sales adding device in the vehicle, such as DVD, audio frequency amplifier, trunk
subwoofer and other non-original accessories, if so, please cut of these system to implement
this test procedure.

Warning!

Warning: Refer to "Warning on Battery Disconnection" in "Warnings and Precautions".

1

Disconnect the battery negative cable. Refer to 2.12.6.1 Battery Cable
Disconnection/Connection Procedure.

2

With a digital multimeter, connect one end to the battery negative cable, the other to
the negative battery.

3

Select digital multimeter's "current test" maximum range.

4

Open the left front door to observe the meter display readings.

Note: Do not carry out any other operations action at this time, otherwise it is likely to damage
the multimeter.

5

If the multimeter has no display, inspect whether the meter is damaged. If there is
displayed reading, close the left front door and press down the engine compartment
button, and then press the remote control door lock button.

6

Observe the body anti-theft system indicator lamp to indicate the system to enter the
warning mode.

7

Wait for more than 10 min to observe the meter readings, (if the multimeter shows an
abnormal reading, tune the multimeter to minimum range). The reading should be
below 30 mA. If the reading is higher than 30 mA, there may be parasitic current.

Note: When the system parasitic current can not be confirmed, compare the vehicle with a
known good vehicle to helping with diagnostic.

5

Make sure that the gearbox is at the neutral position.

Warning: The bridge connection cable must be intact without exposed wires, otherwise it will
cause unnecessary personal injury or vehicle damage.

6

Connect one end of the red cable to the positive terminal of the battery with sufficient
capacity providing the power, and confirm that there is no contact with other metal
parts.

7

Connect the other end of the red cable to the positive terminal of the flat battery. Do
not connect the red cable to the negative terminal of flat battery.

Warning: Do not connect the bridge connection cable directly to a flat battery negative terminal
to prevent the spark and possible battery gas explosion.

Connect one end of the black cable to the negative terminal of the battery with
sufficient capacity providing the power.

9

Finally, connect the other end of the black cable to the flat battery engine ground, and
at least 500 mm (19.7in) away from the discharging battery.

10

Start the vehicle with fully charged battery and run the engine speed at an intermediate
speed for more than 3 min.

11

Start the vehicle starter with flat battery.

12

Dismantle the bridge connection cables in reverse order.
